Expertise in the compounding of engineering plastics and a proprietary process for polymerizing polyphenylene sulfide (PPS) resin free of chlorine and sodium are the backdrop of a new joint venture between Teijin Chemicals Ltd. (Tokyo) and SK Chemicals (Seoul, South Korea) to manufacture and market PPS resins and compounds in July this year. A 12,000-tonnes/yr production plant will be up and running in the fiscal year starting in April 2015.
The joint venture, in which Teijin Chemicals will hold a 34% share and SK Chemicals the remaining 66%, will construct a PPS resin plant in Ulsan, South Korea. As demand grows, capacity at the plant is eventually expected to reach 20,000 tonnes annually. An existing pilot plant will be utilized for market and application development until the new plant starts operating.
PPS resin is primarily is used for components in the engine bay, components related to electric motors, electrical components, connectors and sockets. Demand for the resin is expected to grow in line with the increasing popularity of electric and hybrid vehicles and the ongoing expansion of electronics markets in emerging countries.
